i Specification of Letters atent No. 12,553,",dated March 20, 1855.

Be it known "that I, CnAnLEs KENrsToN, of`Boston, county of `Suffolk,the'Statefof p Massachusetts, have` invented a new and useful Improvement,` inl `Printing-Presses; and `Il do hereby declarefthe following is a"cfull` andfexact description thereof, reference being had to the jaccompanymg drawing, and

p to the letters of referencer marked thereon.

*The advantage fmy press has `over others now 1n use, `for the same purpose, 1t being i so constructed there is "an extended arm on `which a piston and type` are attached the same operating upon `a swivel, the whole being attached toa solidbed. Therelare twopads attached to said `bed,"one. for' the purpose of inkingvthe type, the other for :the article to be placed when printing. The op- V erator byturning saidparm over the pads, and striking a lightblow` upon the top' of the piston alternately,will ink, and print,

withfthe accuracy thatno other press has done.` Another advantage 'in its favor,'th`e t operator, can at pleasure, make animpression upon any partno the article he chooses.

In this process `there `is no blurring of the its construction and" operation. i Figure l, is a plan "ofthe entire machine -or press. Fig.`2, is a section elevation is cut and corresponding with the line in plan F ig.` 1,.X, `X. FigJBis a plan which correspondswith the part of Fig. 1, marked g, e,

Fig. 4, is a plan represents an arm on va line of X, X, of Fig. l, and covers Fig. 3.

The letter A, is the handle of piston B, there being attached at its end a` die marked G., the whole having a reciprocating motion through the arm D.

The letter C, is a spiral spring is at- .tached or surrounds the piston B, for the purpose of giving the die an open position.

The letter D, is an extended arm which has an oscillating motion and turns upon the bed F, F. The bed F, F, is intended to hold the pads H, H, also supports the arm D.

The letter h, is a pin for the purpose of keeping the pads in their proper places.

The set screw a, operates in slot b, gives the piston a steady anddirect motion. The set screw g, holds firmer the die in its socket. t

The letter d, represents a check pin, and the catch e, allows the arm D, to oscillate at a given distance. t

What I claim as new and desire to secure 'by `Letters Patent is.- The arrangement and construction of the press as herein described.
